Did you know that your UK residence and domicile status impacts how much UK tax you are liable to pay? Not only will maintaining a UK non-resident status affect your UK tax exposure, so too does the date you decide to return and become a UK resident again.

If you are UK resident but not domiciled in the UK (i.e. you have a permanent home abroad) you will only be liable for UK tax on the income and gains made in the UK. Provided certain conditions are met, your overseas income and gains can be excluded from UK tax liability. However, this is a complex matter and you should consult the services of an overseas tax planning specialist to avoid unknowingly breaking any tax laws.

Tax Rules for Non-Residents:

Personal Tax Allowances

Regardless of your domicile status, any income sourced in the UK is liable to tax. However, as a non-resident UK national you are still entitled to the same personal tax allowances as a resident. This can be set against any UK income that you may have including bank interest, rental income and pensions.

Disregarded Income

Non-residents are liable to pay UK tax on any income with the following exception. Disregarded income refers to any dividends or interest earned. As a non-resident, the tax liability cannot exceed the combined sum of tax withheld on disregarded income along with the person’s tax liability, if those allowances had been ignored. It’s a complicated issue and if you are in any doubt, take expert expat tax advice on your particular circumstances.

Capital Gains Tax

Capital Gains Tax (CGT) may apply when you sell your home abroad or other assets such as shares that attract capital gains tax as opposed to income tax. You need to calculate your residence status in the same way as for income tax, as laid out below. In short, UK residents are liable to pay tax on UK and foreign income/gains. However, non-residents only pay CGT if they return to the UK or if they sell UK land or property.

Once you have been a non-UK resident for more than five complete years, there are considerable tax benefits when it comes to overseas income and worldwide capital gains. These are exempt from UK taxation unless there is a disposal of UK land, property and assets as part of a UK trade.

Why is understanding my residence status important?

There are many instances when it could be beneficial to secure or maintain being non-UK domiciled. For example, when it comes to Inheritance Tax, if you are UK domiciled then your worldwide assets fall under the scope of UK Inheritance Tax regardless of your UK residency status. However, if you are not UK domiciled, only your UK assets are liable to Inheritance Tax.

How to Calculate your residence status

Working out whether you are a UK resident for tax purposes depends upon several factors. All calculations should be made within the same tax year (6 April to 5 April), not a calendar year (from January to December).

The basic rules are that you are considered a UK resident if you spent more than 183 days in the UK. Alternatively, you are a UK resident if your only home is in the UK and you owned, rented or lived in it for at least 91 days total, 30 of which must have been in the tax year in question.

On the other hand, you are a non-resident if you spent fewer than 16 days in the tax year in the UK. You are also non-resident if you work abroad full-time and spent less than 91 days in the UK (including a maximum 30 days working).

For those working abroad, a few days extra in or out of the country could radically change your residence and tax status. In such cases it is advisable that you consult a specialist in expat tax matters.

Residence in more than one country

In some cases you can be considered a resident in the UK and in another country at the same time. This is known as dual residency. When it comes to tax law, every country is different so you should take expert tax advice. In some cases, countries operate a double tax treaty with the UK. This means that if you pay tax on an earned amount in one country you will not be liable to pay tax on the same amount in your other country of residence.

If you move to or from the UK during a tax year you can have it calculated as a split year. In this instance you only pay UK tax on foreign income during the time you were living in the UK.

Filing a non-resident tax return

You need to inform HMRC when you leave the country or become non-resident. However, you may still be liable to pay tax on UK income including pensions, rental income, bank interest and any earned income. You may need to complete a self-assessment tax return to declare this income. However, you do not need to inform HMRC if you have already claimed tax relief under the UK double taxation agreement.
